This article presents four new possible images of drums in the Finnish rock art, and
considers these, and apparent dancing images as an acoustic record of the past. It also presents
preliminary results of testing echo at over 100 rock-art sites that suggest that exceptional soundscape
is an elemental, if not a fundamental component, of rock art. Both the images and the
echo correlate well with the local Sámi ceremonies of singing and drumming at sacred sieidi
sites—regional tradition and Finnish rock art point to entering into deeper trance through music
and dancing. However, in Finland, there are few entoptic signs in rock art. In some places these
signs are connected to shamanism but research shows a correlation with entoptic signs and psychedelic
substances but not necessarily with shamanism. This disconnect emphasizes the need
for redefining ASC: the term is not singular, but plural. Contrary to being hallucinations, shamanic
states can be better understood as being exceptionally present and part of an Indigenous
knowledge formation process. A pattern of liminal features, images, and local analogies construe
Finnish rock-art sites effectively as sites of liminality, trance, and relationship.
